Security researchers have recently uncovered security issues known by two names, Meltdown and Spectre. These issues apply to all modern processors and affect nearly all computing devices and operating systems. All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at the time of this writing. Apple says Spectre and Meltdown vulnerabilities affect all Mac and iOS devices. There's no complete software patch for Spectre right now, said Michael Daly, chief technology officer of. How to Stop the Meltdown and Spectre Patches from Slowing Down Your PC Chris Hoffman @chrisbhoffman January 17, 2018, 6:40am EDT The Windows patches for Meltdown and Spectre will slow your PC down.
Business Insider. Apple released new updates for older versions of its Mac operating system to protect against the Meltdown and Spectre attacks. The company had previously issued a patch for macOS High Sierra, the most recent version of its Mac operating system, but it put out a new update for High Sierra also.
The updates shouldn't cause the rebooting problems that some PC users experienced after installing similar fixes for Meltdown and Spectre. If you've got a Mac running an older version of Apple's computer operating system, you can now download a software patch to protect your device from the Meltdown and Spectre attacks. Apple on Tuesday issued for macOS Sierra and OS X El Capitan, the two versions of its computer operating system that preceded macOS High Sierra, which the company released last fall. Although the company had previously released a fix for High Sierra to protect against Meltdown and Spectre, it also released a new update for that version of macOS on Tuesday to address the vulnerability that can be exploited by both of those attacks. Intel on Monday its latest patches for Meltdown and Spectre, because those fixes can cause computers to reboot unexpectedly. However, an Apple representative said these latest updates for macOS and OS X don't include Intel's faulty code and shouldn't trigger the reboot problem.
The Spectre and Meltdown attacks are made possible by an underlying vulnerability related to a feature called speculative execution that's been used by nearly every computer chip found in PCs, tablets, and smartphones made over the last 20 years. The attacks, which became public earlier this month, could allow a malicious actor to exploit that vulnerability and get access to the secret data that's on a computer, including passwords. Intel chips, which underly not only most Windows PCs but Apple's Mac computers, are particularly vulnerable to the Meltdown attack. Florence Fu/Tech Insider Apple has another patch for Spectre in the works To protect against those attacks, Mac users running OS X El Capitan should look for version 10.11.6 in the updates section of the App Store app on their computers. Those running macOS Sierra should look for version 10.12.6. The newly released version of High Sierra is 10.13.3.
With the updates, Apple is protecting against Meltdown and one version of the Spectre attack, the company representative said. The faulty patches issued by Intel address another variation of the Spectre attack, but one that is more of concern to cloud computing service providers, the representative said. Apple computers aren't widely used in cloud providers' data centers; still, the company has a fix for that variant in the works, the representative said. 'Not to minimize the risk. We are still planning to issue a mitigation,' the representative said.

Graz University of Technology Security flaws are unwittingly competing to outdo each other. The latest, called Meltdown and Spectre, have the potential to be some of the most widespread yet. It's likely they will impact all computer processors on the market and completely eradicating them will take a serious amount of time. Both Spectre and Meltdown have the ability to be one of the biggest tech security vulnerabilities discovered. Easily ranking alongside,. Since this story was first published, it has been updated with more information about patches for Spectre and Meltdown.
The most recent update covers Apple's macOS system. Here's what we know so far.
The issues were first reported. So, what do the vulnerabilities do? As with all major vulnerabilities of recent times, this pair of attacks has. 'These hardware bugs allow programs to steal data which is currently processed on the computer,' it explains. It's possible for data to be stolen as the vulnerabilities allow for software to read the memory of other running programs. While Spectre and Meltdown technically can be exploited in different ways, they both allow for the isolation an operating system should have to be broken. In theory, they allow data to be stolen from any running programs: passwords, documents, emails all have the potential to be taken.
Are they being used? At the moment, there have been no reported uses of Meltdown or Spectre in the wild. Researchers have described uses of the vulnerabilities, which means it is possible they could be replicated by someone or a group wanting to exploit the problems. Spectre is harder to exploit than Meltdown. Should I be flustered? If you're an IT administrator you should definitely be hot under the collar.
Vendors of products affected include: AMD, Apple, ARM, Google, Intel, Linux Kernel, Microsoft, and Mozilla. Thankfully, for those with an 'Intel inside' there's a patch that can mitigate the problems.
As a result, manufacturers have already started to issue updates for their systems. Everyone with an impacted device should install the updates from its creators as soon as possible. Patches could slow down a machine by as much as 30 per cent. Intel has the performance drop findings saying they're over-exaggerated. But, overall, if the Meltdown updates aren't installed then there's the potential for Meltdown to be used in the real-world and data being stolen. We've listed the patches below. By Amit Katwala There's a catch though; a fix for Spectre hasn't been created.
Short of one being made, the only way the issue will be fully eradicated is with new microprocessors. It seems unlikely that manufacturers will ship replacements for the millions of machines affected. This could leave us with the unsatisfactory result of Spectre only being fully fixed when all affected products aren't used anymore. Given the reliance on legacy hardware by companies and governments, this could easily be another decade. CERT, which deals with and catalogs cybersecurity issues, assessed Meltdown and Spectre rather bluntly.
'Fully removing the vulnerability requires replacing vulnerable CPU hardware,'. What patches are there? Google: The firm is in the process of issuing an for its devices and products. Android will get an update on January 5, Chrome on January 23 and some affected Chromebooks had a mitigation in its OS 63, which was released in December. Microsoft: The company says a patch has been made available for Windows 10 machines and it will automatically be applied.
For older operating systems, reports, a fix will be available next week. Microsoft the majority of its Azure infrastructure has already been updated. Apple: Apple has revealed that all of its Macs, iPhone and iPads have been affected by Meltdown and Spectre. In a, it revealed the vulnerabilities can be used against its devices. On January 23 it completed the patches for its products. The versions with fixes for Metldown and Spectre are listed on its.
For iPhones and iPads iOS 11.2.2 is needed, which came out in early January, for machines running macOS High Sierra and El Capitan there are. Linux: The operating system has a patch. Amazon: Its web services, which underpin a large amount of the internet, have all been updated,.
